T0 @ZZ whom, it may concern.:

Be it known that i, THOMAS O. MCMURTRAY, a citizen oi' the United States, residing at Yazoo city, in the county of Yazoo and State of Mississippi, have invented a new and valuable Car-Coupling Machine, of which the following is a specification.

My invention relates to car-couplings; and it consists in certain improvements in the construction ot' the same, as hereinafter described and claimed.

In the accompanying drawings, Figuie l is a central vertical longitudinal section of my improved car-coupling. Fig. 2 is a side view of the same. Fig. 3 is a plan view of the same. Fig. 4 illustrates the coupling-pin and a detent pivoted thereto.

A designates a draw-head, which is slotted and formed with interior inclined surfaces, as shown, to receive and permit the movement of a coupling-pin and weighted slide, as hereinafter set forth.

G indicates an elevator-block, which is placed on the top of the drawhead, and is perforated to receive the couplingpin and slotted to receive a weighted slide, B. The block G rests over the central slot in the drawhead, and is connected with the draw-head by arms F. The said arms F are pivotally connected with the forward part of said block by a bolt, f, and extend downward and rearward to the projections K on the sides of the drawhead, where they are pivotally secured to the draw-head by a bolt, j", as shown in the drawings, the projections K forming bearing-surfaces for the ends of the arms F. The said block G is further connected with the drawhead by means of the arms E, the forward ends of said arms being connected by a bolt, e, with lugs on block G at its rear end, and the rear ends of said arms being connected with lugs on the drawhead by bolts 'e'.

The coupling-pin C passes through an aperture in bloc-k G and through the slotted draw-head, as shown. The weighted slide B is made substantially in the form shown, with an in clined edge in its lower part, so that when the parts of the coupling are in the position shown in Fig. l and the linl: D is drawn the slide will be raised, as indicated in dotted lines. The forward lower part of the slide closes against the coupling-pin C. The slide i B is hung to the block G by a pin or bolt, l), and extends down through the slot in said block into the draw-head.

J indicates the stop or check lug, which is secured to the top. of the draw-head at its rear end, and is provided with a spring, H, which. is made fast in position in trontot the checklug.

\Vhen the block G and slide B are resting in position as seen in Fig. l, and the link D is pressed against the coupli 11g-pin C, the said block and slide are immediately raised on the pivoted arms E and F, which approach a vertical position, thus allowing the link to enter the draw-head, and the block and slide, mow ing rearward, come in Contact with spring Il and lug J, and are pushed forward and return to their Vformer position, the coupling ot' cars being thus automatically effected.

The head ot' the coupling-pin C has pivoted thereto a hook or detent, L, which in its normal position connects with a catch, Z, on the block G, as shown in Fig. l, and prevents the coupling-pin from being forced upward by the slide B, when the latter is raised, by the link D pressing against the inclined edge thereof.

y A branching chain, M, for use in uncoupling, is connected with slide B and pin C, a short chain being connected with the detent L, so that when the chain M is drawn the detent will be raised before the pin is drawn upward.

l claiml. The combination, with thc drawhead, ot a block resting thereon, a coupling-pin passing vertically through said block and draw head, and oblique arms having` their ends pivoted, respectively, to said block and drawhead, whereby the coupling-pin maybe with drawn independently of the block or by rais in g the arms, substantially as described.

2. The combination, with the slotted draw head, of a coupling-pin, a slotted movable block mounted on the draw-head, a weighted slide capable of independent bodily vertical movement in said block, and a series of arms connected with said block and with the drawhead, substantially as and for the purposes described.

3. In combina-tion with the draw-head, a movable block, G, a coupling-pin, and a IOO arms Connected With the block and with the adapted to connect with a oato11,l,withwhieh draw-head, and a stop or cheek lug, J, prosaid block is provided, substantially as set vided with a spring, said lugbeing in position forth and described. to stop the movement of the said block on said m y U v r pivoted arms, substantially as set forth.
